Open A document without the Open/save/Cancel disloguw box

Hi All
>
I have a datagrid - buit dynamically from a database table - which
contains a column with links to many documents. When the user selects
a link I want them to be able to open the document within the browser
window. This works well. However whenever the link is selected the
user is presented with a File Downloads Dialogue box with the options
Open/Save/Cancel. I want to open the document and give teh user no
options to save.
Is this possible and if so How do I achieve it.
Thanks in advance for all help offered
